Stuttering on external display

Just did a fresh install of Bazzite 3.5.0 which includes the new Nvidia 555.58 drivers as standard

No output from the eGPU, so I installed and ran all-ways-egpu. After running through their guided setup process, this what I get from all-ways-egpu status:


All-Ways-eGPU Main Menu

  1. Guided Setup
  2. Manual Setup
  3. Disable a GPU (Method 1)
  4. Set boot-vga Flag (Method 2)
  5. Set Compositor Specific Variables (Method 3)
  6. Help
  7. Version
  8. Uninstall all-ways-eGPU

The line:
Unknown device “/dev/dri/card1”: No such device
is a bit worrisome
